Abstract

La présente invention concerne un véhicule à enfourcher qui est très sensible aux entrées et qui réduit la transmission de vibrations du moteur au corps de châssis. Le véhicule à enfourcher selon la présente invention comprend le corps de châssis, une unité d'entraînement, une roue d'entraînement et une unité de génération d'énergie. Le corps de châssis constitue une structure de châssis de véhicule. L'unité d'entraînement comprend un moteur d'entraînement qui reçoit une puissance électrique et délivre une puissance de moteur. La roue d'entraînement est entraînée par une puissance de moteur fournie par le moteur d'entraînement. L'unité de génération d'énergie comprend un moteur pour la génération de puissance et un générateur de puissance. Le moteur pour la génération de puissance ne transmet pas de puissance de sortie à la roue d'entraînement. Le générateur de puissance est fixé au moteur pour la génération de puissance et est électriquement connecté à un support de transmission de puissance électrique présentant une flexibilité. Le générateur de puissance convertit une puissance de moteur fournie par le moteur pour la génération de puissance en puissance électrique et fournit une puissance électrique au moteur d'entraînement. Par conséquent, le véhicule à enfourcher est configuré sous la forme d'un véhicule hybride à configuration en série dans lequel le moteur pour la génération de puissance est soutenu de manière oscillante par la structure de châssis de véhicule et l'unité d'entraînement est soutenue par la structure de châssis de véhicule séparément du moteur pour une génération de puissance.
